Ensuring resilience and safety of the transportation system of Kyiv in planning the network of road tunnels

Abstract

The analysis of risk mitigation in the transport infrastructure of the Kyiv city by using a system of car tunnels was conducted, their ranking and construction priorities were determined. The main considered structural and functional factors included: district type, downtown factor, population density, daily pendular movement, arterial network density, average traffic speed at peak hours, surface connectivity, surface road throughput, criticalness, vulnerability. The modified morphological method, involved in the research, took into account the military (terrorist) threats, along with the groups of ecological and technogenic risks. This approach might be useful for the development of the urban paradigm in the geopolitical frontier zones. Additionally, a morphological analysis/analytical hierarchy process hybridization was suggested that provided an alternative point of view with a slightly different ranking of tunnels compared to the basic model. For evaluation of the morphological model parameters, satellite imagery and geospatial Urban Atlas for Kyiv products were used as independent sources of geospatial data. The combination of these diverse datasets enables a deep understanding of the complex, interconnected systems within a city. By utilizing these products and the developed morphological models, the cities’ community can become safer and more resilient, driving the evidence-based transport policies.
